MORRIS POLLAK, OF NEW'YORK, N. Y.

BRACELET.

SPECIFICATION forming part of Letters Patent No. 240,924, dated May 3,1881.

Application filed March 11, 1881.

To all whom it may concern:

Be it known that I, MoRRIs POLLAK, of the city and State of New York,have invented an Improvement in Bracelets, of which the following is aspecification.

Bracelets have been made with hinged segments and a clasp; but as thisclasp is liable to become disconnected it is usual to use a guardchainfrom one segment to the other. in some instances the hinge has beendispensed with and the bracelet made of sections upon ellipticalspring-wires, and in other instances a thin blade of metal has beenadded to the clasp, the same passing into the opposite segment, andhaving a head to limit the distance that the bracelet can be opened.

My invention is available with the ordinary bracelet having hingedsegments; and it consists in the combination, with such hinged segments, ofone or more helical cxpansible springs and a connection passingthrough that spring to the opposite segment, so that the expansiblespring acts upon the segments to draw them together, thus dispensingwith all clasps or guard-chains, and rendering it impossible to separatethe segments of the bracelet, so as to render it liable to drop off thearm and become lost.

In the drawings, Figure 1 is a section representing a bracelet with myimprovement, the segments being slightly open. Fig. 2 is a sepa rateview of the springs and connecting-strip, and Fig. 3 is a section of thehinge portion of the bracelet in enlarged size.

The segments a and I) are hinged together at c, and these segments areto be of any desired size, shape, or material, and they may be more orless ornamented. Each section is either hollow or formed with a tubularcavity passing most of the distance around from the free end toward thehinge.

The helical springs c e surround the connection 6, which connection isin theform of a wire, flat strip, or chain. There are also around thewire or other connection 1' abutment-blocks o 0, against which the innerends of the springs press,and the outer ends of the springs arefirmly'connected to the connection 2' by solder (N0 model.)

or otherwise. These parts are to be placed within the hollow bracelet,or within the cavity provided in the bracelet for their reception, andthe abutment-blocks 0 0 are secured into the bracelet-sections, neartheir moving ends. This may be done by solder,or by pinning, or in anyother convenient way. The springs being always under a slightcompression, they tend to close the bracelet; butit' the sections areswung on the hinge so as to open them, then the wire or strip connectiont keeps the outer ends of the helices attheir uniform distance apart,and the movement of the abutment-blocks 0 with the segments of thebracelet causes the springs to be compressed; hence they will exerttheir force to close the bracelet as soon asliberated. The chain, strip,or wire, as the bracelet is opened, draws out of the bracelet andcompresses the spring or springs, and these act by expansion to closethe bracelet again.

I rem-a rk thattwo helical springs, one in each segment of the bracelet,are preferable, but if the necessary amount ot'opening movement can beobtained only one spring may be used, the other end of the strip, wire,or chain being fastened to the segment of the bracelet that does notcontain any spring.

The abutment-blocks 0 0 may be removed, if necessary, for repairs of thesprings or the connecting wires, strip, or chain, by withdrawing thepins or the abutments, or one of them, may be remo vabl y connected tothe bracelet by passing such abutment behind fingers or catches, thespring forcing such abutment against the fingers or catches.

I claim as my invention The combination, with the hinged segmentsforming the bracelet, of a connection passing from one otthe movingsegments into the other, and a helical spring andabutmentgfgiiibstantially as specified, whereby the spring aets to closethe bracelet, as set forth.

Signed by me this 5th day of March, A. D.
